The authors have proposed dispersing Calcite nanoparticles in to the stratosphere to decrease solar irradiation without changing earth's emission by long infrared. We may achieve the dispersion of the particles by launching 10-tons of particles 19 times per day from 100 launch sites located in the world. In this report, a feasible design of a projectile is proposed to disperse 10 tons of nanoparticles at the altitude of 30 km. We can accelerate the 20 m long, 15 tons of projectile in an acceleration vacuum tunnel of 34 km up to 1000 m/s by using superconducting linear motors. When the projectile is launched at the altitude of 3500 m. By unfolding sailwings at the altitude, the projectile can keep level flight during dispersing the particles in the stratosphere.
